CARPET-WIRE BLADE-IIIJSERTING MACHINE.

Application filed May 28,

The object of my invention is to provide new blades to carpet wires, of the class used for cutting strands to produce knap or pile In carrying out my invention I provide a reciprocative member to push blades into po sition in the carpet wires, the blades preferably being supplied in a stack in a magazine or holder, a movable support for the wires adapted to be moved into register with the blades to receive the latter, means to GJGCt used blades from the wires as the latter are moved toward blade receiving position, and means to move the support with a wire from and to blade receiving position.

My invention also comprises novel details of improvement that will be more fully hereinafter set forth and then pointed out in the claims.

Fig. 8 is a detail section on line 8, 8, in Fig.1, and

Fig. 9 is a detail perspective of the blade ma 'azine.

S imilar numerals of reference indicate corresponding parts in the several views.

The carpet wire is indicated at A, which is of any usual or well known construction, shown provided with arecess or slot at at the blade receiving end, inwhich the blade B is located and retained by means of the springacting stop a, (Fig. 7). At 1 is indicated a 1927. Serial No. 194,895.

suitable support shown in plate-like form. means to remove used blades from and apply A reciprocative member or pusher 2 is shown supported by 'an d projects from a head 3 that is reciprocatlve in a guideway 1 carried by support 1. The guideway is shown provided between suitable blocks 5, 6, 7 and 8 carried by, the support, whereby the parts 2 and 3 may be reciprocated, An operating member 9 is pivotally carriedat- 10 upon a support 1 and shown provided with an arm 9 for manipulating it and with an arm9 pivotallyconnected by link 11 with block 3, whereby when the member .is rocked the block will be reciprocated to advance and retract the member 2. At 12 is a magazine or holder shown secured upon block or guide way cover 8 by screw 13, in which magazine the blades B are located in stackedrelation over an opening 8 in the part 8, beneath which opening is a rest 14 for the blades, the reciprocative member 2 being adapted to operate over said rest to push blades successively from the stack through the delivery end of the guideway, (Fig. 2). In order conveniently to handle the stack of blades B, I

provide a blade-holder shown comprising a flat piece of metal C having its end portions 0, 0 bent reversely, in hook-like form, to en gage the adjacent corners of the triangularly shaped'blades, and the sidewalls of the magazine 12 are'provided with vertical recesses 12 in which the portions 0, 0 of the holder C-maybe slid for conveniently locating the stack of bladesin the magazine, (Fig. 9) A retainer D having its ends, (Z bent laterally is adapted to be fitted-against the plate C with the ends 05 opposing the upper and lower blades B of the stack for temporarily retain-, 1

ing the blades so that when the plate C with the blades has been'placed in the magazine the retainer D may be removed so that the bladesmay feed downwardly, whereby each. time that the reciprocative member 2 is pushed under the stack a blade will be forced for the wires A to retain their bent ends a" in position for the blades B to slide thereover. The wire A is clamped and held at an acute angle tothe feed of blade B so as to position the stop lug a below the plane of the blade, which will flex to pass over said stop lug to enter slot a in the wire, (Fig. 2 Said rctainer is shown in the form of a stud 17 ournaled on the support 15 and having a finger piece 17 for rotating it, the stud being re-- tained by means of a nut 18, (Fig. 2). The retainer 17 is shown provided with an cccen tric annular edge portion 17 and a flange 17' over the latter, whereby the tainer may be rotated to present the narrow part of the eccentric 17 opposite the guide- Way 15' to permit the insertion into and the removal of wire A from said guideway. When the retainer is rotated farther its greater eccentric portion will push the wire against the back of the guideway and the flange 17 will overlie the wire to retain it in firm position with its recess a in opposition to the guideway 4 in position to receive blade B whenpushed from said guideway, (Fig. 1.) The blade support 15 is operative by the actuating member 9 in correspondence with the operation of the reciprocative member 2, for which purpose I have shown a rod 19 pivotally connected at20 with arm 9 of member 9 and slidable in a bore in a stud 21 journaled on an arm 15 projecting from member 15. A spring 22 upon said rod opposes stud 21 and also opposes a nut 23 on rod 19, whereby the tension of the spring may be adjusted, a nut 24 on the outer end of the rod being adapted to bear against the stud for actuating member 15 in one direction, the the spring 22 serving to resiliently actuate member 15 in the opposite direction and permit sliding of rod 19. An arm 25 is pivotally supported at 26 and is provided with a grooved roller 27 at the free end adapted to engage the sides of the'blade adjacent to the cutting edge with the latter in the groove of the'roller so as not to be dulled, (Fig. 6). A spring 28 secured at 29 normally presses arm 25 and its roller toward blade B, and a stop 30 engaging said arm limits the movement of the roller toward the blade, (Figs. 1 and 3). The siring pressed roller 27 tends to guide the lade and keep the back of the blade snugged against the adjacent portion of guideway 4 when the blade is being pushed from the latter into the wire A.

A blade ejector is indicated at 31 shown comprising an arm pivotally supported at 32 on support 1 and normally retained by a spring 33 (connected with said ejector and said support) against a stop 34 on said support, (Fig. 1). The ejector 31 is located so that the member 15 with the wire A may pass beneath the ejector and said ejector is provided with a downwardly extending lug 31", located adjacent to one side of the ejeclVhcn a blade is to be removed from a carpet wire A and another blade inserted in the wire the operating member 9 will be moved to approximately the position shown in dotted lines in Fig. 1, whereupon the carpet wire support 15 will be also moved to the dotted position shown in said figure opposing a gauging stop 37 on support 1, audthe reciprocative member or pusher 2 will. be fully retracted from beneath the stack of blades. The wire A will. then be placed in its support 15 and the tip end of the wire will be brought against gauge 37 to position the wire and the latter will be fastened by the retainer 17. The operating member 9 will then be rotated toward the full line position shown in Fig. 1. As member 15 is moved with member 9 the ejector lug 31 will engage the blade in the wire and cause its ejection from the wire, (Fig. 4), and continued movement of member 15 will cause it to pass under spring finger 35 and bring the member to rest against stop 38 with the wire in position to receive a blade, and continued operation of member 9 will cause the reciprocative member 2 to push the lowermost blade in the stack into the recess a in wire A to a position behind the stop a of the wire, (Figs. 3 and. 7). The member 9 next will be moved toward the dotted line position in Fig. 1, and as the member 1 is correspondingly moved said member 15 will engage spring finger 35 and cause the ejector 31 to be swung around on its pivot 32 to the dotted line position without engagement of the blade edge with said spring finger, and during such movement of the ejector its lug 31 will be moved in advance of the blade on the carpet wire so as not to interferewith the latter. When the member 15 has re leased the finger 35 the ejector will be swung back against stop 34. by spring 33 to the full line position in Fig. 1. The carpet wire A having the blade attached may be removed from member 15 and a new wire inserted, and

so on.

In accordance with my invention old or used blades may be removed from carpet wires and new blades fitted in said wires successively and expeditiously, whereby economy in time is effected in the operations, handling of the blades by the operator is avoided, and the blades will all be accurately set in the wires.
